With all the buzzes on evolutionary discoveries, I shall start a thread that deals with it.
So that I could keep track of datings they love to keep changing and call that science. Not that they don't admit it, but that I would have enough facts to be eloquent about it.
On the note of "improving" dating ancient rocks/artifacts, it is not the change that is the problem, it is the attitude towards having the wrong answer earlier that matters.
Starting with this:
Oldest rock on Earth found in Australia. (4.374 Bil years)
Methanosarcina 252 million years ago vs. Yucatan Asteroid (or comet?) 65 million years ago
Though they are different theories for different periods, the bacteria causing extinction is a new one that debunked the asteroid theory for that age. It's good to keep improving, but to make science better than religion is a joke and irresponsible.
